How to debug pod failure on EKS?

Question

Hello there.  
  
I'm currently using EKS v1.11.5 (control plane only) and just noticed that one of my pod failed a week ago.  
  
Kubernetes automatically created a new pod right away, so there was no downtime, but still want to debug what really happened.  
  
I tried to get logs from the failed pod but it only returned me container

```
"" in pod "" is not available
```

Is there any way to track down this problem deeply? Like kubernetes audit-logging from control plane?   
  
Thanks.  
  
+ Maybe something left on syslog of worker nodes, but I blocked ssh connection to nodes for security reasons. so it's not possible for now.

Answer

As long as you have not removed the pod you could do

```
kubectl describe pod ....
```

It should indicate why the pod failed, could be due to OOM or other resource failure etc.
